ShoreMaster Infinity 5-Sided Dock Posts (3’ to 8’) – Aluminum Dock Leg Pipes

ShoreMaster Infinity 5-Sided Dock Posts are engineered to deliver superior dock stability, easy seasonal adjustment, and long-lasting performance for standing dock systems. Designed for use with ShoreMaster Infinity Series dock leg pockets, these innovative aluminum dock legs feature ShoreMaster’s exclusive 5-sided design, which creates three points of contact inside the leg pocket for a more secure and stable fit than traditional dock posts.

Sold individually, these dock posts make it easy to replace a single leg or build out a complete dock system based on your specific needs.

Compared to conventional round or square dock legs, ShoreMaster’s 5-sided dock posts help reduce movement, shifting, and wobble, giving your dock a more solid feel in changing water conditions. Constructed from lightweight, corrosion-resistant extruded aluminum, these dock posts are built for long-term freshwater use and are easy to handle during installation, removal, and seasonal dock adjustments.

We offer ShoreMaster Infinity 5-sided dock posts in lengths from 3’ through 8’ to accommodate a wide range of water depths and installation requirements. Please note that the 8’ option is manufactured at 94" actual length so that it can ship via standard UPS or FedEx parcel service rather than common carrier freight.

Compatibility Information

These dock posts are designed specifically for ShoreMaster Infinity Series dock systems and provide the best fit and performance when used in ShoreMaster Infinity dock leg pockets. However, because the posts feature a standard 2" x 2" profile, they may also be suitable for other dock systems or custom applications that accept similar square post dimensions. Fitment should always be verified before use in any non-ShoreMaster application.

Why Choose ShoreMaster 5-Sided Dock Posts?

ShoreMaster’s unique 5-sided leg design offers a real performance advantage over traditional dock legs. By creating three points of contact in the leg pocket, these posts help improve dock rigidity and minimize shifting in use. That added stability can be especially beneficial in areas with soft lake bottoms, changing water levels, or heavier foot traffic.

For dock owners looking for a reliable, easy-to-adjust, and premium-quality dock leg solution, ShoreMaster Infinity 5-Sided Dock Posts are an excellent choice for both replacement and new dock installations.
